SPECIFICATION forming part of Letters Patent No. 606,236, dated June 28, 1898.

Original applioationled January 1G, 1897, Serial No. 619,452. Divided and this application tiled September 2, 1897. Serial No. 650,386. (No model.)

To @ZZ whom, t may con/cern:

Be it known that I, ADoLrHUs PETERSON, a citizen of the United States, residing at Lansdowne, in the county of Delaware and State pet, wall-paper, and the like, andiis what I- prefer to term a myrioscope, and has for its obj ect to provide positive and effective means whereby a series of samples may be automatically exhibited, one after the other, and when so exhibited will give a lrealistic appearance of a surface of indefinite extent being covered with `the material of a design or a pattern; and a further object of my invention is to cause the patterns or samples to dwell through a suflicient space of time t-o permit careful inspection thereof7 after which they will move onestep, bringing the next pattern into position, which will then dwell for a similar purpose, and so on throughout the entire series of samples. Y

A still further object of my invention is to so construct the apparatus as to provide for the ready application of stop mechanism, which may be under the control of the observer, in order that at any time the'operations of the machine mayrbe arrested and there held until the desired observation is had by simply pressing abutton; and this invention is a division of application for Letters Patent Serial No. 619,452, dated January' 1G, 1897, and intended to accomplish in a different manner the same objects set forth in said application.

Vith these ends in view this invention consists in the details of construction and combination of elements hereinafter set forth and then specifically designated by the claim.

In order that those skilled in the art to which this invention appertains may understand how to make and use the same, the construction and operation will nowbe described in detail, referring to the accompanying drawings, forming a part of this specification, in which i Figure l is a section of an apparatus made in accordance with my present invention,

i showin g the endless belt or apron upon which samples may be secured; Fig. 2, an enlarged detail View of the mechanism for bringing about the movements of the endless belt carrying' the samples, and Fig. 3 a plan view of the mirrorebox and feed-roll.

In carrying out my invention as here embodied I provide a mirror-box A, of any suitable design, having mirrors A' arranged upon the innerwalls thereof. A dri-ve-roll B is so arranged that the belt C passing therefrom and over the guide-rolls D and E will pass through the mirror-box, as clearly shown in Fig. l, and this belt then passes upward and over the guide-pulleys E and G and linally around the guide-pulley H, by which arrangern'ent `a suitable length is had to the belt for the securement of a large number ofl samples thereto. The drive-roll B has an extended spindle I, upon which is mounted the Worm J, having' secured thereto the pulley K. This Worm and pulley revolve independent of the spindle, using the same only as a bearing. The worm meshes with the worm-wheel L, Which carries a cam M, having an offset N, adapted to act upon the roll O, journaled in the upperend of the lever P, the lower end of this lever being forked and embracing a clutch Q, which is splined on a spindle, and this clutch is provided with suitable teeth for en gagment with the teeth R, so that when the clutch is thrown into engagement withthese teeth the spindle will be caused to revolve with the worm and when Withdrawn from said teeth the spindle will remain at rest, while the worm continues to revolve, and with it the wormwheel. The result of this is that when power is applied to thepulley K by a suitable belt or otherwise the worin-wheel will be revolved, While the drive-roll II remains at rest until the offset N of the cam, acting upon the roll, has forced the clutch into engagement with the teeth R. After this the drive-roll will revolve so long as the roll O remains in contact with the offset; but when said offset has passed from out of contact with the roll a suit able spring R/ will draw the clutch out of engagement with the ,teeth R, causing the drive-roll to again dwell, while the remaining portions of the apparatus continue thei r` movements. These movements aresotimed that samples carriedbythe belt will be drawn suc- IOD cessively Within the mirror-boxin proper relative position thereto, dwell, and remain therein the desired length of time and then be withdrawn therefrom, while another sample is substituted therefor. This will be continued so long as the pulley is revolved, thereby exhibiting all the samples in turn and then reexhibiting the same, and thus continuing indefinitely.

Since the apparatus is especially adapted for show-windows and the like, it is sometimes advantageous that a number of samples be exhibitedat one and the same time, and I therefore here show themirror-box as divided into two sections by a partition T, which may have mirrors on each surface thereof, and, if desired, a number of such compartments may be formed in the mirror-box by the latter being extended. Thus a window may be so fitted with this apparatus that observers may be attracted by the constantly-changing patterns and when standing to observe the same may, without waiting for one pattern to be withdrawn and another pattern substituted therefor, look into one compartment or the other, thus seeing two or more patterns, as desired.

A simple method for arresting the movements of the belt at any time by the observer is to use an electric motor for the driving of the pulley K and conveniently arrange a button for the shutting off of the current of said motor, vsince by this method the mechanism of the apparatus would be in no wise disarranged; but of course any other convenient method might be used for this purpose.

It will also be seen that an additional belt of samples can be conveniently exhibited by the same mirror-box by running it across and underneath the other. In such cases both belts have in some suitable place a sufficient space cut out the size of the inner surface of the box, so that when one belt is at rest with said open space under the box the view of the pattern on the other belt passing underneath is not interfered with.

Having thus fully described my invention, what I claim as'new and useful is In a device of the character described, a mirror-lined box having its sides terminating a slight distance from the bottom, a shaft journaled parallel with the sides, an extension formed with said shaft, a pulley, a sleeve formed therewith, said pulley and sleeve bein gloosely mounted on the extension, a wormscrew formed on the sleeve, a worm-wheel journaled at right angles to the shaft meshing with the worm-screw, a cam-{iange formed on the face of the wheel, a centrally-pivotedd lever carrying a roll bearing against the side of the flange, a clutch splined on the shaft embraced by the other end of the lever, whereby said clutch will bev moved longitudinally of the shaft to engage and disengage the end of the sleeve by a corresponding movement of the lever, a roll journaled on the shaft, idle-rolls journaled parallel with the 'firstnamed roll, and an endless belt run over said rolls and through the mirror-box, as and for the purpose described.

In testimony whereof I have hereunto affixed my signaturein the presence of two sub scribing witnesses.
